IMPROVED DUMPING-WAGON The Schedule referred to in these Letters Patent To all whom it may-concern.-

Be it known that I, WILLIAM H. S TEARRE'TT, of .Wilmington, in the county of Newflastle, and State of 'Delaware, have invented certain new and useful Improvements in DumpingJVagons; and I do hereby description of the same, referencebeing. had to the accompanying.drawings, making part of this specification, and in which- Figure 1 represents a vertical longitudinal section Figure 2 represents a similar section,.the wagonbody being shown in the position as dumped. Figure 3 represents a plan or top view; of the run-' ning-gear of the wagon, showing the horizontal slothe body of the wagon. i Figure 4 represents a vertical transverse section of Figure 5 represents an elevation of one of the springs and sn p portiu g-plates detached from the wagon.

Myimpro-vement relates to the employment of horizontal supporting-plates, secured directly to the springs in such manner that the wagon-body may be both. supported upon and locked to the plates, and thelat-ter, the springs, and the axle, turn with the wagon body, whereby the dumping of the wagon is greatly facilitated; in providing the horiby the bodyof the wagon is both locked to and slides .upon supporting and turning plates; in a wagon, having its rear axle connected to and turning with the axle, by curved hinged connecting rods; and also the arrangement upon a front truck-frame of atransverse roller, for running the body of the wagon back upon the snppoitingplates, to dump the load.

In the accompanying drawings-f A represents thefront truck of thefrimning-gearof the wagon, which may be constructed in any approved manner, to which is connected,by'king bolt, the front supporting-frame B of the wagon.

The axle O, of therear supporting-wheels D, is secured to semi-elliptical springs E, to which are secured horizontal plates F, upon which the wagon-body is both supported and locked. y I

These, plates, with'their springs, are secured permawith the. dumping of the wagon-body G, and they are of a length a little greater than that qt the springs, and are provided with anti-friction rollers a, at each They are also provided 'with slots b b, fig. 3, arranged in the same line, and of twosections, into each of which project pins c, from. the lower parallel rails of the wagon-body. r

the springs and their fore united with the hinges I, so as to thereon, and by and making part of the same.

Thelower ends of .these rails are fitted with plates (1, which constitute the ways of the wagon-body,'and

supporting-plates must therefore be arranged a distance apartequal to that of the ways.

The pins 0, which project into the slots 1) b of the supporting-plates, are provided with heads, which fit against the under side of said snpportin -plates F,

0 thereby locking thebody of the wagon to the plates, and the slots are of a length to admitof the proper degree of movement of the wagon-body to effect the dumping.

Each end of the slots, therefore, forms a bumper, and limits'the movement of the wagon-body-upon the plates.

From theforegoing, it will beobserved that while the body G is locked to the supportingplates F, it is free-to move back and forth thereon. I

This arrangement also admits ofthe axle being fixed to the springs and plates, but for which arrangement, the body of the wagon would have to be run-back to the end of the springs, in order to dump 'it,'which '0, tothe' underside of the supporting-plates, and at their rear ends are confined, so as to be free to slide against the said plates, to permit the yielding of the sprm gs.

The supporting-plates F being fixed directly to the axle 0, the latter serves as the turning, and this'irrespectiveot' plates, as the plates, the springs,-aud the axle turn with the movement of the body, by which it will be seen that the entire weight and jar in bringing the wagon-body back to a horizontal position after the load is dumped-, is borne alike on both ends of the supporting-plates and the axle, and not upon one end of the springs only, which arrangement adds greatly to the durability of the springs, and facilitates the operation of dumping.

axis of the body in its position upon the The rear axle 0 being arranged to turnwith the body of the wagon, the tront-truck-f1-a|ne A. is thererear axle by two connecting-rods, H, secured to the front supporting-frame B, and hinged to the said rear axle.

These connecting-rods are curved upward from their permit the front wheels to pass nnder them in turning the wagon.

The front supporting-flame B is provided with a' smallfroller, J, secured in frame, and in such lower rails of .the

suitable bearings across the position as that the ways d of .the wagon-body, when down, will rest means of'a crank, K,-applied to the end of this roller, which projects beyond the frame for this purpose, the wagon-body may be started in its movement to dump the load, or moved upon its ways the length of the slots 1) b, to effect the dumping.

The wagon-body is locked to the supporting-plates F in such a position that the weight thereof" will preponderate forward, and its front end. is fastened by hook, or in any suitable manner, to the front supporting-frame.

A pinion on the roller J, matching into a rack on the wagon-body, may be used.

Having described my invention,

I claim- 1. The combination of the springs E and the turning axle O, to which they are secured, with the horizontal supporting andlockiug-plates F, for the wagon-body, constructed and arranged substantially as described.

2. lhe.horizontal plates F, having supporting-rollers a at each end, and slots 7) b, by which the body is both supported upon and connected with the plates, by the locking-pins c, in the manner described.

-3. The curved connecting-rods H; secured to the front truck-frame, and hinged to a rear turning axle, O, in the manner described.
